Frozen Embryo Transfer Calendar
FET Cycle Protocol

The sample FET schedule and calendar below is for frozen embryo transfer of blastocyst stage embryos.

  • A frozen transfer cycle of day 3 embryos is similar, usually with 2 days less progesterone exposure prior to transfer.
  • This sample calendar shows the timing of the medications, monitoring of uterine lining development, and procedures.
  • Variations from this schedule are often done. Some IVF clinics give a shorter or longer duration of estrogen exposure before starting progesterone.

Key to FET IVF calendar:

Lupron = subcutaneous injection of a medication called Lupron (GnRH agonist). This medication is taken once daily. It prevents the woman from ovulating during the FET cycle - which would throw off the timing of uterine receptivity.

Blood and ultrasound = blood test for estrogen and progesterone levels and transvaginal ultrasound to measure the endometrial thickness in the uterus.

Estrogen = this hormone stimulates the endometrial lining to develop and thicken. It is usually given as either skin patches or oral tablets.

Progesterone = vaginal cream or suppositories or intramuscular injection of a medication (female hormone) called progesterone. This drug helps to prepare a receptive lining for embryo implantation.

Embryo transfer procedure = procedure to put embryos in the uterus


Frozen embryo transfer success rates - what are the chances of frozen embryo transfer working?

  • This depends on several variables
    • Age of the woman
    • Quality of the frozen embryos
    • Stage of the frozen embryos (day they were frozen, usually day 3 or day 5-6)
    • The quality of the uterus and how it is prepared for the FET
    • The IVF lab's embryo freezing protocol and their expertise with cryopreservation

Cost of frozen embryo transfer

  • Our frozen embryo transfer cost is $4000 plus medications. This includes the entire FET cycle - all monitoring on the female, as well as thawing, culturing and transferring the embryos.
